the act of hitting a guy in the nuts, usually by girls. they find it funny, but from my own personal experience it hurts more than getting shot. not only that but after the pain u feel terribly sick. women should be hit in the boobs afterwards, the equilizer has been discovered my brothers, reach out and strike thy breasts!
